Warwickshire maintained their 100pc record in the Twenty20 Cup with a 68-run victory over Glamorgan as the first short-format fixture in Birmingham attracted a crowd of 10,500 to Edgbaston.

The buoyant Bears made 181 for nine and dismissed Glamorgan for 113 to sentence the Welshmen to a third consecutive defeat in the new competition.

The Dragons looked as if they meant business when Matthew Maynard carved Waqar Younis' first ball for six but a half-century by the former captain was all they had to offer in another below-par performance.

Maynard drove another six from the ball before he was caught behind for 50 off Collins Obuya and the Kenyan leg-spinner went on to put Warwickshire in complete control in a spell of five for 24.

Michael Powell was the only other significant contributor for Glamorgan with 22 as the National League champions again failed to adapt to the high-speed formula. They have won all five games this season in defence of their First Division title but are the only county without a win in the three Twenty20 groups.

Their bowling was hit all over the ground as Warwickshire reached a formidable total from a flying start of 95 in 11 overs by their left-handed openers, Nick Knight and Neil Carter.

Knight completed his second half-century of the week and Carter made 47 from 31 balls, a personal best in one-day cricket, after hitting three of the 11 sixes in the home team's innings.

Former England spinner Robert Croft conceded 19 runs in his first over but recovered well to claim the first three wickets at an overall cost of 42.

The breakthrough came when Carter holed out to deep square leg and, in Croft's fourth and final over, a return catch removed Knight for 54 and Dominic Ostler top-edged a reverse sweep. Darren Cosker's left-arm spin also became a useful weapon with a couple of successes as Warwickshire lost six wickets in adding 42 in a frenzied finish in the last four overs.

Ian Bell was bowled by Mike Kasprowicz after hoisting two sixes - one of which was caught by a spectator to win two free flight tickets - and Neil Smith's two scoring shots comfortably cleared the fence. Matthew Dennington emerged as Kent's star performer as they beat Essex by three wickets at Chelmsford. The 20-year-old seamer reduced a packed crowd of 6,000 to silence as he destroyed the Essex middle order on his way to figures of four for 28.

His efforts helped tumble out the home county for 116 in 18.4 overs, but Kent were made to work hard before reaching the winning post with 3.5 overs to spare.
